python – Is there a method to write metadata to an image in PyExifTool?

I used ExifTool‘s ‘-tagsFromFile’ to copy Exif metadata from a source image to a destination image from the command line. Wanted to do the same in a python script, which is when I got to know of PyExifTool. However, I didn’t find any command to copy or write to a destination image. Am I missing something? Is there a way I can fix this?

I found user5008949‘s answer to a similar question which suggested doing this:

import exiftool
with exiftool.ExifTool() as et:
    et.execute("-tagsFromFile",  filename , "dst.JPG")

However, it gives me the following error:

Traceback (most recent call last):
  File "", line 9, in <module>
    et.execute("-tagsFromFile",  filename , "dst.JPG")
  File "/home/radha/venv/lib/python3.6/site-packages/", line 221, in execute
    self._process.stdin.write(b"n".join(params + (b"-executen",)))
